"Method and device for winding up. Of Square braid ".

The present invention relates to a method and apparatus for winding of square woven, with the individual rows of stitches are pushed together in the longitudinal direction, _a ß d this can be wound into rolls "

The pushing together of the rows of lashes according to the invention is possible because in a square braid, each row of stitches is pushed into the adjacent row of stitches can be so that the length of the braid is reduced without increasing its thickness su. These Compression can, of course, occur during the upwelling can also be done manually, but this operation is difficult and only provides imprecise results «

The "present invention consists of an improved Method and a device for unwinding Viereokgafleeht, after which this by a simple mechanical operation is pushed together »

"This is done by the fact that the braid is mechanically attached to a moving document is abandoned, whereby the speed of movement of the base in relation to the speed at which the braid touches the base is abandoned, is different, whereby the braid is pushed together in the longitudinal direction and condensed into one iiolle can be used up.

The object of the invention is shown in the accompanying drawing For example showno Ss shows:

According to Figures 1, 2 and 3, the machine contains a number endless belts 1, which are arranged side by side, and each of which has an upper run 2, which between the front and rear guide pulley J and 4 runs.

Each band has a considerable slack, so that its upper circumference 2 can hang down between the hollows 3 and 4, as shown in FIGS which · should have condensed mesh roll, variable. Each belt runs over the front and rear guide rollers 3 and 4 and, in our opinion, the guide rollers 5 and 6, which keep the lower or the return strand of the belt outside the area of the upper ..rumms 2 and far below the passage of this upper drum . The roller 5 is also adjustable in order to increase or decrease the passage of the belts 1 according to the desired diameter for the compacted roll. The tapes 1 are a auo flexible but non-stretchable _f stable katerial as r, ₀ -S 'canvas made. If the width of the braid to be wound is not that large, only one band is required. For wider mesh or different mesh widths, it is advantageous to use a plurality of bands having different widths and which are mounted side by side, so that there are between them gaps 7 where guides may engage to hold the ends of the compressed braided role ₀ One can of course also provide interchangeable ribbons in order to adapt them to the respective widths of the braid

Provided teeth 9, the task of which is to intervene in the mesh of the square braid and to promote this, wherein each pin is bent backwards in order to be able to better release the braid when it comes off the roll. Another guide roller 10 is provided, over which the braid runs from the roller 8 into the trough, which passes through the upper run 2 of the endless belt 1 is formed. The roller 10 is provided with wreaths 11 which serve to guide the edges of the square braid. These wreaths are arranged along the holle 10 slidably so that they can be adjusted to the number and width of the correspond to the braided rolls to be wound. A similar guide roller 12 with rings 14 is used to feed the Square braid on the feed roller 8.

The guide rollers 3i5 | 6, 10 and 12 are freely rotatable, while the feed roller 8 and the guide roller 4 are driven mechanically. The guide roller 4 is driven at a lower rotational speed than the feed roller 8, in that the rotational movement of the feed roller is transmitted to the guide roller via a reduction gear 15. The reduction in speed by engaging the reduction gear 15 is chosen so that the desired amount of longitudinal compression of the mesh is achieved. A reduction of a little less than 50 i <> is best suited for normal square mesh.

The Viereckgefleoht the feed roller can be supplied to 8 of a hell that lies in a roller bed 17, which is provided with freely rotatable rollers 18 can thus freely rotate the roller 16 while it is on ₀ the mesh passes over the guide roller 12 on the feed roller 8, which it rests on the upper run of the belt 1, where it hangs down between the guide rollers 3 and 4. As it runs off the feed roller 8, the square braid moves down over the front of the guide roller, being guided between the rings 11, after which it is picked up by the upper webs 2 of the endless belt 1, which automatically wind it up into a roll, such as this is identified by the number 180 in FIG.

When the braid leaves the guide roller 8, it is in the normal stretched state according to FIG the braid is picked up by the endless belts 1, it experiences a reduction in its running speed, which pushes it together in its longitudinal direction, whereby the adjacent Masohenreinen a and b (Fig and 6) can be shifted into each other. At the same time, as a result of the passage of the upper strand, the braid becomes endless Ribbons 1 rolled up. The bands adapt to the increasing diameter of the should

To complete the wound roll, the last layer is brought into the normal stretched state and so with it Wire fastened so that it lies tightly against the roll on all sides. «The finished roll is made by the endless Tapes 1 removed from the machine with the aid of mechanical lifting devices, as shown in FIGS. 1 and 2 denoted by the number 19

Instead of the direct supply from a roll 16, as shown in Figures 2 and 3, the square braid can also be fed directly from a braiding machine. This possibility is illustrated in FIG. 4, wherein the braiding machine is identified by 20 and 8 represents the feed roller described. The machine 20 belongs a pin roll 23, with the help of which the braid is pulled out of the machine. Still belongs to the machine a roller 24 with an automatic device for starting and stopping the pin roller 23. To the A tensioning roller 21 is used to coordinate the feeding activity of the roller θ with the operating speed of the braiding machine 29 arranged so that it can move so far under the action of a spring or a weight, how this is necessary to ensure the passage of the braid web from the outlet side of the machine 20 to the feed roller 8 balance. By moving the tension roller 21, an automatic control device is actuated through which

the drive of the feed roller 8 takes place with interruptions.

The winding machine shown in FIG. 4 is the same but has the essentials of the embodiment according to FIGS. 1 and 31 only one guide roller 22 instead of the two guide rollers 5 and 6 »The rolled-up mesh roll 180 is again taken from the revolving belts, as already described

FIG. 7 shows another solution, according to which a tensioning roller is arranged so that it can be brought from a zero position ει r into a working position a, _r 1, in which it tensions the belts 1 and thereby the wound roller 180 Iu one position brings, from which it can be easily rolled onto a transport vehicle without lifting.
